Anyone in the Atlanta area with an early 944?

I think I may have a bad DME. I replaced the ref/speed sensors, ignition switch, DME relay. I'm getting 12v through the red with yellow stripe wires to the DME. Good contuinunity from the sensors to the computer. Cleaned all the grounds, one under the dans, the one at the firewall, and the battery ground. I resoldiered all the joints on the sticker side of the DME. The only thing I see left is the DME! I'm about $200 into this with no improvement, in fact it's worse. It would start most of the time, now it's not started in about a week. Also there is no tach bounce of course. I would like to put my DME in someone else's car to see if it'll start before I buy one.
